Old and rare and durable are nice. IF not since supplanted by objectively superior products. Only discontinued legends I would crave are non-electronic, and almost all non-mechanical. The exception would be Mouli manual tin rotary cheese grater. When it comes to grating the Parm, steel sucks, stannum rules. All others are kitchen and garden hand tools not since matched or replicated, much less exceeded. You'd have to pay me to take an old Pioneer receiver. Put it in an effing museum.
